Avant-garde shoot-'em-up Sine Mora is this week's addition to the Instant Game Collection on PlayStation Plus. Subscribers will be able to freely download the Vita version of the collaborative project from Grasshopper Manufacture and Hungarian studio Digital Reality when the PS Store updates later today.

Also dropping anchor on PSN this week is an array of discounts on horror games. The Halloween sale includes scary good deals on terrifying titles like Fatal Frame, which Plus subscribers can net for just $2.00.
